Easy issue to solve since the fiber spool doesnt have to be attached to the remote controller… all a drone following fiber back would spot is a router looking thing at best.

Tensile strenghth is definitely enough. Ive used fiber to tow vehicles before in a pinch. A single strand takes a surprisingly higher amount of force to break than one would expect. Good luck pulling a window pane in two…

None of your points are even remotely close to an actual problem, let alone a serious one lol

My scissor begs to differ.
